Basic Test

The basic test of the phased-array Doppler sonar velocity system made by us indicates that the positioning errors are large. From the positioning result, it can be known that compass error is the dominant factor. Therefore, to improve the measurement precision of compass and revise its course deviation is one of the keys to improve the accuracy of Doppler positioning. From the speed processing result, it shows that the positioning accuracy can be further improved through averaging the speed (smoothing).
